  • A number of studies have evidenced the effect of modifiable lifestyle factors such as diet, breastfeeding and nutritional status on breast cancer risk. However, none have addressed the missing data problem in nutritional epidemiologic research in South America. Missing data is a frequent problem in breast cancer studies and epidemiological settings in general. Estimates of effect obtained from these studies may be biased, if no appropriate method for handling missing data is applied. We performed Multiple Imputation for missing values on covariates in a breast cancer case-control study of $C{\acute{o}}rdoba$ (Argentina) to optimize risk estimates. Data was obtained from a breast cancer case control study from 2008 to 2015 (318 cases, 526 controls). Complete case analysis and multiple imputation using chained equations were the methods applied to estimate the effects of a Traditional dietary pattern and other recognized factors associated with breast cancer. Physical activity and socioeconomic status were imputed. Logistic regression models were performed. When complete case analysis was performed only 31% of women were considered. Although a positive association of Traditional dietary pattern and breast cancer was observed from both approaches (complete case analysis OR=1.3, 95%CI=1.0-1.7; multiple imputation OR=1.4, 95%CI=1.2-1.7), effects of other covariates, like BMI and breastfeeding, were only identified when multiple imputation was considered. A Traditional dietary pattern, BMI and breastfeeding are associated with the occurrence of breast cancer in this Argentinean population when multiple imputation is appropriately performed. Multiple Imputation is suggested in Latin America's epidemiologic studies to optimize effect estimates in the future.

  • This study reviews the concept and characteristics of the deconstruction philosophy in order to analyze the major aspects of the fashion world called the deconstruction fashion based on the deconstruction philosophy, and analyzes the works of Jean Paul Gaultier in terms of Derrida's deconstruction theory. The scope of this research is from 1980 to present, and this study fashion on the many kinds of literature on philosophy, aesthetics and literary criticism, and the domestic and international fashion journals and magazines. The deconstructionism is the philosophical theory which denies the traditionally recognized logocentric metaphysical theory and refuses the closed world and pursues the open world, opposing the dichotomic theory which is the deep-rooted tradition of the Western philosophy. The results of analyses centering on the internal deconstruction trend expressed in the works of Jean Paul Gaultier are as follows. 1 The past style combined with the present appears in the form of the entirely new trace, not the past emotion and meaning in Gaultier's works transcending the time and space. 2 Gaultier presents the unconventional intermeaning of meanings, producing various possibilities according to the wearing method of the wearer by layering several clothes. 3. Gaultier breaks from masculinity and femininity in the intertextuality of gender, and decomposes the fixed idea of men's or ladies'wear through the design sharing bisexual text. 4. In the intertextuality of T.P.O., Gaultier presents the problem of how to wear by mixing different items through obscuring the division of the nature of time, space, and purpose. Especially Gaultier can be called the first designer who, worthy of the father of the deconstructionism, has introduced in the fashion making inner wear like outer wear. 5. In the intertextuality of coordination, Gaultier presents a new perspective of coordination through free combination and contrast, raising a question about the man-made harmony criterion and deconstructing the clothes. On the other hand, Gaultier expresses the intertextuality of the material through the heterogeneous combination of the material. 6. The decomposition trend expressed in the many works of Gaultier reflects an open mind presenting a new perspective through the distortion of the form, exaggeration, and break from the existing construction method. 7. The decentering trend in the works of Gaultier is found to deconstruct the Western-dominated elements against the background of subcultural elements, the elements borrowed from the minority race, md the Oriental culture. 8. The discontinuity clothes of Gaultier present the disordered principle of design without the uniform rules, and express the unrestrained freedom without captivation by the preconceived idea through the disruption of the dress and its ornaments just like Gaultier.

  • Gourd seeds were irradiated with the doses of 0-20 Gy to investigate the effect of the low dose $\gamma$-radiation on the early growth and physiological activity. The stimulating effects of the low dose y- radiation on the early growth were not noticeably high, but were increased generally at 4-16 Gy irradiation group. The catalase and peroxidase activity of cotyledon from seeds irradiated with $\gamma$- radiation were increased at 8 Gy irradiation group. The photochemical activity of leaf was noticeably high at 4 Gy irradiation group. The photochemical yield of PSII, estimated as Fv/Fm, decreased with increasing illumination time by 50% after 4 hrs in the control and 8 Gy irradiation group, while Fo slightly increased. However, Fv/Em in the 4 Gy irradiation group decreased by 40% of inhibition, indicating that photoinhibition decreased by the low dose $\gamma$- radiation. Changes in the effective quantum yield of PSII, $\varphi_{PSII}$ and 1/Fo- l/Fm, a measure of the rate constant of excitation trapping by the PSII reaction center, showed similar pattern to Fv/Em. NPQ decreased by 70% after photoinhibitory treatment with showing similar pattern between the control and the irradiation group. These results showed the positive effect of low dose $\gamma$- radiation on the seedling growth and the reduction of photoinhibition in the 4 Gy irradiation group.

  • The present study examined the effects of Korean white ginseng (WG, Panax ginseng C. A. Meyer) on the learning and memory function and the neural activity in rats with trimethyltin (TMT)-induced memory deficits. The rats were administered with saline or WG (WG 100 or 300 mg/kg, p.o.) daily for 21 days. The cognitive improving efficacy of WG on the amnesic rats, which was induced by TMT, was investigated by assessing the Morris water maze test and by performing immunohistochemistries on choline acetyltransferase (ChAT), acetylcholinesterase (AchE), cAMP responsive element binding protein (CREB) and brain derived neurotrophic factor (BDNF). The rats treated with TMT injection (control group) showed impaired learning and memory of the tasks, but the rats treated with TMT injection and WG administration produced significant improvement of the escape latency to find the platform in the Morris water maze at the 2nd and 4th days compared to that of the control group. In the retention test, the WG 100 and WG 300 groups showed significantly increased crossing number around the platform compared to that of the control group (p < 0.001). Consistently with the behavioral data, result of immunohistochemistry analysis showed that WG 100 mg/kg significantly alleviated the loss of BDNF-ir neurons in the hippocampus compared to that of the control group (p < 0.01). Also, treatment with WG has a trend to be increased the cholinergic neurons in the hippocampal CA1 and CA3 areas as compared to that of the control group. These results suggest that WG may be useful for improving the cognitive function via regulation of neurotrophic activity.

  • This study was designed to investigate the effects of sea tangle (Laminaria japonica) extract and fucoidan components on anti-aging action. Sprague-Dawley(SD) male rats (210$\pm$5g) were fed experimental diets Dasi-Ex group: sea tangle extract powder of 4.0% added to control diet; Fuco-I, II and III groups: funcoidan powder of 1, 2 and 3% added to Dasi-Ex group for 45 days. Hydroxyl radical (.OH) formations were significantly inhibited (10-20% and 25-30%) in serum and brain mitochondria of Dasi-Ex and Fuco-I, II and III groups compared with control group. Significant differences in .OH formations of brain mitochondria in Dasi-Ex and Fuco-I groups could not be obtained, but.OH formations of brain microsomes resulted in a significant decrease (15-20%) in Fuco-II and III groups compared with control group. Basal oxygen radical (BOR) formations were significantly decreased about 10% and 13-15% in brain mitochondria of Dasi-Ex and Fuco-I group, and Fuco-II, III groups, and also decreased about 10% and 15-20% in brain microsomes of Dasi-Ex and Fuco-I groups, and Fuco-II, III groups. LPO levels of brain mitochondria and microsomes were significantly inhibited about 10% in Dasi-Ex and Fuco-I, II groups and 15% in Fuco-III groups. Oxidized proteins (>C=O) were significantly inhibited about 10% in serum of Dasi-Ex and Fuco-I, II, III groups and brain mitochondria of Dasi-Ex group, while remarkably inhibited (30~35%) in brain mitochondria of Fuco-I, II and III groups. Nitric oxide (NO) levels were significantly inhibited (12~15%) in serum of Fuco-I, II and III groups, but there no significant difference in serum NO levels of Dasi-Ex group. Superoxide dismutase (SOD) activities were remarkably increased (30~ 60%) in serum of Fuco-I, II and III groups, but there were no significant differences in SOD activities in serum of Dasi-Ex group. Catalase (CAT) activities were significantly increased about 20% in serum of Dasi-Ex and Fuco-I, II, III groups. Mn-SOD activities in brain mitochondria were significantly increased about 17% in Dasi-Ex group, while remarkably increased 26~36% in Fuco-I, II, III groups. Cu,Zn-SOD activities in brain cytosol were dose-dependently of fucoidan increased 10%, 12% and 18%, respectively, compared with control group. These results suggest that anti-aging effects of fucoidan may play a pivotal role in attenuating a various age-related changes such as chronic degenerative disease and senile dementia.

  • The yeongok stream originates at the natural park, Mt. O-dae and flows to the East Sea of korea, normally maintaining I or II grade of water quality and its average water flux is 352,100 ㎥/d. However, the typhoon 'Rusa', which occured on 31 August 2002, changed its watercourse and configuration, and the ecosystem was deeply damaged. Moreover, the hydrological characteristics were once more transformed, and the ecosystem was secondarily damaged during repair-work of destroyed bridges and elevations. After the flood disaster, the species diversity diminished 17% for attached diatom and 44% for aquatic animals. However, the earth and sand, dug from river bed during intensive repair-work throughout the entire stream, made diversity drop to 32% for the diatom and the aquatic animals were wiped out. Especially, fishes were totally destroyed except for some species such as Moroco oxycephalus in the upper stream. The yeongok stream has little contamination source and short water residence time due to the short length and rapid slope, and consequently a temporary deterioration of water quality caused by repair-work may be rapidly recovered, but it needs a long time to restore the damaged ecosystem.

  • This study investigated effect of extract containing quercetin-3-O-${\beta}$-D-glucuronopyranoside from Rumex Aquaticus Herba (ECQ) against chronic gastritis in rats. To produce chronic gastritis, the animals received a daily intra-gastric administration of 0.1 ml of 0.15% iodoacetamide (IA) solution for 7 days. Daily exposure of the gastric mucosa to IA induced both gastric lesions and significant reductions of body weight and food and water intake. These reductions recovered with treatment with ECQ for 7 days. ECQ significantly inhibited the elevation of the malondialdehyde levels and myeloperoxidase activity, which were used as indices of lipid peroxidation and neutrophil infiltration. ECQ recovered the level of glutathione, activity of superoxide dismutase (SOD), and expression of SOD-2. The increased levels of total NO concentration and iNOS expression in the IA-induced chronic gastritis were significantly reduced by treatment with ECQ. These results suggest that the ECQ has a therapeutic effect on chronic gastritis in rats by inhibitory actions on neutrophil infiltration, lipid peroxidation and various steps of reactive oxygen species (ROS) generation.

  • $\beta$-Galactosidase($\beta$-D-galactoside galactohydrolase, E.C. 3. 2. 1. 23) from E. coli K-12 CSH 36 was immobilized on porous cellulose beads which were previously activated with tannin and p-benzoquinone. Their general properties and applicational possibities were investigated. The most effective, enzyme immobilization was obtained when tannin and p-benzoquinone, pH 11.0, were used together as activation reagents and a period of 6 hours of activation. The optimum pH of $\beta$-galactosidase was 5.5 for free enzyme and 6. 0 for the immobilized enzyme, the optimum temperatures for native and immobilized enzyme were both $50^{\circ}C$. Kms of native $\beta$-galactosidase and immobilized enzyme for ONPG(o-nitrophenyl galactopyranoside) were about $4.0{\times}10^(-4)M$ and $7.5{\times}10^(-4)M$, respectively. In the case of tannin : p-benzoquinone activated cellulose beads, the immobilized enzyme retained over 80% of the initial enzyme activity after 20 runs, which is very promising result far a possible industrial application.

  • This study examined the effect of formulated diets (composed of condensed freshwater $Chlorella$ or $Schizochytrium$ sp., $Crypthecodinium$ sp., and EPA oil sources derived from baker's yeast) on the population growth and fatty acid composition of the brackish water flea ($Diaphanosoma$ $celebensis$) to determine diet effectiveness for mass production. Results indicated that the highest maximum density, fecundity, and population specific growth rate (SGR) of the flea were observed using a diet of $Tetraselmis$ $suecica$ (control). However, results using condensed freshwater $Chlorella$ and the mixed treatment of $Schizochytrium$ sp.+$Crypthecodinium$ sp.+EPA oil did not significantly differ from the control treatment ($P$>0.05). Thus, $T.$ $suecica$ could be replaced with a combination diet of $Schizochytrium$ sp., $Crypthecodinium$ sp., and EPA oil in condensed freshwater $Chlorella$ without growth interruption of $D.$ $celebensis$. As the percentage of combination diet (mix of $Schizochytrium$ sp., $Crypthecodinium$ sp., and EPA oil) in condensed freshwater $Chlorella$ increased, the level of ARA, EPA, DHA, and n-3 HUFA in $D.$ $celebensis$ also increased. However, the population density of $D.$ $celebensis$ sharply decreased with the use of treated supplements C5M5 (CHL [50%] and $Crypthecodinium$ sp.+ $Schizochytrium$ sp. + EPA oil [MIX 50%]). The optimum proportions of CHL and MIX for $D.$ $celebensis$ within the mixture were 70% and 30%, respectively. Based on the results, the combination of $Schizochytrium$ sp., $Crypthecodinium$ sp., and EPA oil in condensed freshwater $Chlorella$ appears to be a stable and effective food source for mass production of $D.$ $celebensis$.
